PCB LTE Antenna 4G Internal Antenna

Description

What is PCB LTE Antenna 4G Internal Antenna?

The PCB LTE Antenna 4G Internal Antenna CTRF-ANTENNA-PCB-7027-4015-UFL100 is an internal PCB antenna with a 3dBi gain 4G LTE antenna manufactured by C&T RF Antennas Inc for GSM, NB-IoT, 3G 4G LTE applications.

The Internal PCB LTE Antenna 4G Internal Antenna comes with a 40x15mm size, 2/4dBi gain, 100mm RG 1.13 cable antenna extension, Ipex/u.FL connector, and self-adhesive sticker for the easy mount to the 4G LTE terminal.

How many ways of the LTE system?

LTE system defines both Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD) in two ways

The working characteristics of the TDD duplexing method make TDD have the following advantages:

(1) flexible frequency configuration, the use of FDD system is not easy to use fragmented frequency band;

(2) The ratio of downlink time slots can be increased by adjusting the uplink and downlink time slot conversion points, which can well support asymmetric services;

(3) With the consistency of upstream and downstream channels, the receiving and transmitting base stations can share part of the RF unit, which reduces the equipment cost;

(4) Receiving the upstream and downstream data without a transceiver isolator, only a switch is needed, reducing the complexity of the equipment;

(5) With. Uplink and downlink channel reciprocity can better use transmission pre-processing technology, such as pre-RAKE technology, joint transmission (JT) technology, intelligent antenna technology, etc., and can effectively reduce the processing complexity of mobile terminals.

The processing complexity of mobile terminals can be effectively reduced.

However, TDD duplex mode also has obvious shortcomings compared with FDD:

(1) Since the time resources of TDD mode are divided into uplink and downlink, the transmitting time of TDD mode is only about half of that of FDD, and if TDD wants to send the same amount of data as FDD, the transmitting time of TDD mode is about half of that of FDD.

If TDD wants to send the same amount of data as FDD, the transmitting power of TDD should be increased;

(2) TDD system uplink is limited, so the coverage of the TDD base station is obviously smaller than FDD base station;

(3) TDD system transmitting and receiving channel is the same frequency, can not be interference isolation, intra-system, and inter-system interference;

(4) In order to avoid interference with other wireless systems, TDD mumbles have to reserve a large protection band, which affects the overall spectrum utilization efficiency.
